Ok, I know its not in Dulwich per sae, but Dulwich Wood toward Crystal Palace did the BEST sunday roast I've had in a long time.... its still maintains the original pub style and hasn't gastroed yet like most pubs in ED. Whilst I dot mind the gastro, an original english old mans pub is so refreshing these days. The Crown and Greyhound in the Village also rocks. But it does sometimes depend on the time of day as to the quality of food you receive - and the mood of the chef too!
